as the Butterley Bulb, used in many early iron steam ships including HMS Warrior In 1861 Alleyne patented a method that allowed hot ingots to be moved around a roller after they had passed by just one person. During the production of steel sections the bar has to be repeatedly put through rollers. Allowing this to happen using just one person was a substantial increase in productivity. By 1863 the company was rolling the largest masses of iron of any foundry in the country. Among its most famous buildings are the Barlow train shed at St Pancras station in London, which included 240-foot spans. Alleyne's next invention was the two high reversing steel mill patented in 1870, which used two steam engines to allow metal ingots to be repeatedly rolled to get the correct size and section. With this technique the steel did not have to be moved to re-enter the rolling process but merely had to be moved back into the rolling machine once it had passed through. There was also an extensive brickworks for railways, thousands of factories and domestic dwellings. By 1874 company workers were starting to fight for better conditions. The company sacked 11 miners "without a charge" on 5 May 1874. In 1885 the Butterley Company made the Grade II listed footbridge for Cromford Station, which was used by Oasis for a photograph shoot for the record sleeve for their 1995 single called 'Some might say.' The Old Godavari Bridge, also known as the Havelock Bridge was constructed with stone masonry and steel girders in 1896 linking Rajahmundry in East Godavari to Kovvuru in West Godavari in Andhra Pradesh,India. It has 56 spans each of 45.7 metres (150 ft)and is 3,480 metres (11,420 ft) long. The girders were fabricated by the Butterley Company of Ripley, Derbyshire. The rail bridge served the busy Howrah-Chennai line until its decommissioning, a century later, in 1997 when a replacement bridge was built at the side of the Old Godavari Bridge. The bridge is being used to host the civic water supply and there are plans for it to be a tourist destination. 20th century At its peak in the 1950s the company employed around 10,000 people. In 1957, a partnership with Air Products of the USA helped establish that company in the United Kingdom. In the early 1960s the company acquired locomotive manufacturer F. C. Hibberd & Co Ltd.
